基于M-CDIO的C语言课程教学研究

提出了基于CDIO工程教育模式的本地化和微型化教学模式(M-CDIO),并将其运用于C语言程序设计课程教学过程中;重新修改和设置了教学目标、教学内容、教学体系、教学方法和团队项目等:课程组织方式以微型项目为导向而不沿用传统的知识点导向,知识内容为集成的而非传统的知识与能力割裂的,等等.这些创新对深化工程课程教学改革具有实际意义.     

Applications of additive manufacturing (AM) in sustainable energy generation and battle against COVID-19 pandemic: The knowledge evolution of 3D printing

Sustainable and cleaner manufacturing systems have found broad applications in industrial processes, especially aerospace, automotive and power generation. Conventional manufacturing methods are highly unsustainable regarding carbon emissions, energy consumption, material wastage, costly shipment and complex supply management. Besides, during global COVID-19 pandemic, advanced fabrication and management strategies were extremely required to fulfill the shortfall of basic and medical emergency supplies. Three-dimensional printing (3DP) reduces global energy consumption and CO₂ emissions related to industrial manufacturing. Various renewable energy harvesting mechanisms utilizing solar, wind, tidal and human potential have been fabricated through additive manufacturing. 3D printing aided the manufacturing companies in combating the deficiencies of medical healthcare devices for patients and professionals globally. In this regard, 3D printed medical face shields, respiratory masks, personal protective equipment, PLA-based recyclable air filtration masks, additively manufactured ideal tissue models and new information technology (IT) based rapid manufacturing are some significant contributions of 3DP. Furthermore, a bibliometric study of 3D printing research was conducted in CiteSpace. The most influential keywords and latest research frontiers were found and the 3DP knowledge was categorized into 10 diverse research themes. The potential challenges incurred by AM industry during the pandemic were categorized in terms of design, safety, manufacturing, certification and legal issues. Significantly, this study highlights the versatile role of 3DP in battle against COVID-19 pandemic and provides up-to-date research frontiers, leading the readers to focus on the current hurdles encountered by AM industry, henceforth conduct further investigations to enhance 3DP technology.     

Teleoperation to robotics at Langley Research Center

A popular conception of the evolution of remote manipulation is a progression from teleoperation to telerobotics and then to robotics. This is logical because in going from teleoperation to robotics there would appear to be a continuous decrease in manned workload, an increase in system complexity, and an increase in the amount of intelligence in the automated system. During the past 10 years NASA Langley Research Center (LaRC) has been involved in all three areas. The decision on which system is most suitable for a task depends not only on the task, but on the allocation of responsibility for intelligence or high level control. The operator may be responsible for all intelligence and control functions, they may be shared between the operator and the automated system, or they may be performed by an autonomous system. This paper discusses some of the experiences in each area in applications related to possible space tasks and some of the lessons learned.

On the history of Ludwig von Bertalanffy’s “general systemology”, and on its relationship to cybernetics - Part II: Contexts and developments of the systemological hermeneutics instigated by von Bertalanffy

The history of “general system theory” is investigated in order to clarify its meanings, vocations, foundations and achievements. It is characterized as the project of a science of the systemic interpretation of the “real”, renamed here “general systemology”. The contexts and modes of its elaboration, publication and implementation are discussed. The paper mostly focuses on the works of its instigator: Ludwig von Bertalanffy. However, general systemology was a collective project: the main contributions of other “systemologists”, from the 1950s until the 1970s, are hence also considered. Its solidarity with the history of the Society for General Systems Research is notably discussed. A reconstruction of the systemological hermeneutics is undertaken on this basis. It finds out the potential systematic unity underlying the diversity of the contributions to this both scientific and philosophical project. Light is thus shed on the actual scope of von Bertalanffy’s works.
